The Chemistry is Right!

NON-ACIDIC, NON-CAUSTIC, PHOSPHATE-FREE Rust Guard's ultra-concentrated formula effectively inhibits rust when applied during or after flushing the car's underside. Like all Kaady products, it's been performance-proven in car washes around the country, including our chain of automatic carwashes in the rainy Pacific Northwest... which acts as a year-round test lab for Rust Guard and the rest of our products.
